Tom Baker Success! - July 16th, 2016So, this is a guy I've been trying to get for a few years. I found out that he now only signs for a fee, so I went to his website and chose the cheapest available size for an actual photo, and selected the best (I like kitties :3) You can choose the dedication. That was about a week ago. He has a very profesional organization- I knew down to the moment he signed the photo. I got it today. I have to say, for the $25 total (with shopping), you get a good deal. Great quality photo, and he even sent the extra mile- signed as "Dr. Who IV" and put his tenure down (which I had not asked for! Fine with me!) Like I said, ordered from website, and received in a week! tombakerofficial.com

TOM BAKER (DOCTOR WHO) - SUCCESS!! - November 12th, 2015I'm a huge fan of the 'Classic' Doctor Who series and my all time favorite Doctor being the fourth, Tom Baker. Tom played The Doctor from 1974 to 1981 - the longest running tenure of any other actor for the part.
Tom's year's in Doctor Who are often referred to as 'The Golden Years', as it was during his run in the series that viewing figures for the show were at there all time high. Many consider this era to contain the best story lines, some of which are now considered 'Classics'.
Tom's now 81 and only autographs for a fee via his website. I didn't mind as I'm such a fan of his work on Doctor Who, I had to add him to my collection. Plus he allows you to choose your own photo to send for him to sign if you wish.
Taken from tombakerofficial.com, in exchange for 10 whole English Pounds I received my own chosen A4 photograph personally autographed by Tom.

Will treasure this success. For me, Tom IS The Doctor.
